I. QUALIFICATIONS SUMMARY OF JEFF L. WOLFE

My background and qualifications are detailed in my curriculum vitae, attached hereto as Appendix 1. In pertinent part, my curriculum vitae reflects nearly thirty years of U.S. Coast Guard service, concluding with my retirement in 2008 as a Lieutenant Commander from U.S. Coast Guard Eighth District, New Orleans. At the time of my retirement, I held the position of Chief, Offshore Compliance Eighth Coast Guard District. In this capacity, I was responsible for administration and execution of U.S. Coast Guard regulatory compliance regime for vessel and production systems operating on the Outer Continental Shelf (OCS) throughout the Gulf of Mexico. Prior to this position, I served for several years as Chief, Offshore Activities and Senior Marine Inspector Marine Safety Office / Sector New Orleans. In this role, I conducted hundreds of safety and security regulatory compliance exams on all types of vessels and offshore facilities, including mobile offshore drilling units, operating in the Gulf of Mexico and overseas. Additionally, I served as an instructor for the offshore regulatory compliance course and taught offshore inspection techniques to new U.S. Coast Guard offshore marine inspectors.

Following my U.S. Coast Guard service, I began consulting for a variety of offshore oil and gas industry participants in the area of regulatory compliance. My clients include, among others, production contractors, offshore supply vessels and facility owners and operators, and pipeline owners. The scope of my regulatory compliance consulting services includes, but is not limited to, the following: vessel design; vessel safety systems; vessel construction and conversion; and vessel operations and maintenance.

II. REPORT OF JEFF L. WOLFE

This report presents opinions and conclusions concerning the seaworthiness, marine systems, and safety conditions present on the Deepwater Horizon on April 20, 2010. More specifically, this report addresses: Regulatory Compliance; Emergency Response and Evacuation; Safety Culture; Vessel Integrity; Fire and Gas Detection and Alarm Systems; and Engines. This report also presents the basis and reasoning for the opinions and conclusions reached on these subjects, including the data and information considered in forming such opinions and conclusions. There may be additional evidence, data, or information supporting the opinions and conclusions presented though not specifically referenced in this report.

In forming my opinions and conclusions, I have relied upon my maritime background; my experience with and understanding of vessel construction, maintenance, and operation; standard accepted maritime practices; and knowledge of the offshore oil and gas industry. A detailed discussion of my background and qualifications is contained below. In sum, between my service in the U.S. Coast Guard and my private sector consulting practice, I have accumulated nearly thirty years of combined marine and offshore oil and gas industry experience, including four years of service in the U.S. Coast Guard as the Chief of Offshore Compliance for all areas of the Gulf of Mexico on which Outer Continental Shelf activities are conducted.

In my cumulative experience, I have boarded and inspected hundreds of vessels, including mobile offshore drilling units and fixed and floating and offshore facilities. In none of these inspections did I encounter a single vessel or facility that I deemed to be in “perfect”

1 condition. For vessels and facilities of this nature operating in a marine environment there are always some deficiencies or corrective actions that could and should be addressed. My opinions and views are, in part, based on my belief that such deficiencies and corrective actions rarely require removal of a vessel from operation, as long as processes are in place to identify and assess the risk and implement mitigating measures, if required, to address identified risks until permanent corrective action is feasible.

In performing my analysis, I note certain limitations in the availability of information and evidence. Namely, as a result of the loss of the vessel, I cannot examine or evaluate the material condition of the rig or equipment onboard. Additionally, certain pertinent documents, both electronic and hard copy, onboard the rig were lost in the incident.

With regard to the scope of my analysis, I have not addressed the well control event or functionality of the subsea / well control equipment, including but not limited to the blowout preventer (BOP).

A. Regulatory Compliance

Upon review of all flag and coastal state certificates, documents, licenses, and status reports from the American Bureau of Shipping (ABS), I conclude the Deepwater Horizon was in full compliance with all statutory, flag, and coastal state requirements. In addition, the Deepwater Horizon was fully ABS-classed in good standing.

1. Deepwater Horizon Vessel History

The Deepwater Horizon was a self-propelled, dynamically positioned, semi-submersible, column-stabilized mobile offshore drilling unit (MODU) built for R&B Falcon Drilling Co. by Hyundai Heavy Industries Co., Ltd. (Ulsan, South Korea) in 2000.1 The Deepwater Horizon was capable of drilling “up to 35,000 ft [10,670 m] at a water depth of 10,000 ft [3,048 m]” in harsh environments.2 While drilling the Macondo well, the Deepwater Horizon was operating in just over 4,900 ft (1,500 m) of water.3 The unit was designed to function 24 hours a day while drilling with its crew operating the complex drilling machinery, propulsion equipment, and hotel services on a 12-hour-on and 12-hour-off basis.4 Individual crew members normally worked a 21-day hitch pattern, consisting of 21-days-on and 21-days-off.5

The Deepwater Horizon was registered in the Republic of the Marshall Islands as a MODU on December 29, 2004.6 From the time of its construction until that date, it had been registered in the Republic of Panama.7

2 2. Regulatory Overview

(a) Flag State

Under Article 94 of the United Nations Convention of the Law of the Sea (UNCLOS), every Flag State shall take such measures as are necessary to ensure safety at sea relating to the construction, equipment, and seaworthiness of the vessel.8 The Republic of the Marshall Islands (Marshall Islands) was the Flag State for the Deepwater Horizon. The Marshall Islands is a party to all major international conventions and other related international maritime instruments.9 These conventions and instruments are described in more detail below.

(i) International Convention of the Safety of Life at Sea

The Deepwater Horizon was in full compliance with the International Convention for the Safety of Life at Sea (SOLAS Convention). The SOLAS Convention in its successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant ships, including MODUs. The main objective of the SOLAS Convention is to specify minimum standards for the construction, equipment, and operation of ships, compatible with their safety. Flag States are responsible for ensuring that ships under their flag comply with its requirements, and a number of certificates are prescribed in the SOLAS Convention as proof that this has been done. Specific requirements address subdivision and stability, machinery and electrical installations, fire protection and fire detection, lifesaving appliances and arrangements, and safety of navigation, among others.

1) Code for the Construction and Equipment of Mobile Offshore Drilling Units

The Deepwater Horizon was in full compliance with the Code for the Construction and Equipment of Mobile Offshore Drilling Units, 1989 (1989 MODU Code). The 1989 MODU Code is an international standard for mobile offshore drilling units. The 1989 MODU Code establishes requirements of the construction and operation of MODUs that are considered equivalent to the requirements of the SOLAS Convention for MODUs.10 The Marshall Islands has specifically adopted the 1979 and 1989 MODU Codes as national regulation and mandated compliance with those Codes and additional requirements found in the Marshall Islands Mobile Offshore Drilling Unit Standards.11 The Marshall Islands issued a Mobile Offshore Drilling Unit Safety Certificate (MODU Certificate) to the Deepwater Horizon that was valid for five years as evidence of compliance with the 1989 MODU Code.12

8 United Nations Convention of the Law of the Sea, art. 94(3)(a). 9 Republic of the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report, at vii. 10 Code for the Construction and Equipment of Mobile Offshore Drilling Units, 1989, Preamble. 11 Republic of the Marshall Islands Mobile Offshore Drilling Unit Standards, Rev. 8/02. 12 Exhibit 3075, Deepwater Horizon Licensing Information, TRN‐MDL‐00171605, 1771.

3 2) International Safety Management Code

The Deepwater Horizon was in full compliance with the International Safety Management Code (ISM Code). The ISM Code is part of the SOLAS Convention. It was made mandatory for MODUs in July 2002. The ISM Code establishes guidelines for the implementation of shipboard and shore-based management systems to ensure the safe operation of vessels and for pollution prevention.

3) Minimum Safe Manning

The Deepwater Horizon complied with all manning requirements. Flag States issue a Minimum Safe Manning Document (Certificate) (MSMD) under provisions of Chapter V of the SOLAS Convention in order to ensure that all vessels are sufficiently, efficiently, and safely manned with properly trained and certified personnel.13 These safe manning requirements are established to ensure that the vessel’s complement “includes the grades/capacities and number of persons required for the safe operation of the ship and the protection of the marine environment."14

(ii) International Convention for the Prevention of Pollution from Ships

The Deepwater Horizon was in full compliance with the International Convention for the Prevention of Pollution from Ships (MARPOL Convention). The MARPOL Convention is the main international convention covering prevention of pollution of the marine environment by ships from operational or accidental causes. The MARPOL Convention includes regulations aimed at preventing and minimizing pollution from ships – both accidental pollution and that from routine operations – and currently includes six technical Annexes, including prevention of pollution from oil, sewage, and garbage among other items.15

(iii) International Convention on Standards of Training, Certification and Watchkeeping for Seafarers

The Deepwater Horizon was in full compliance with the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW Convention). The STCW Convention prescribes minimum standards relating to training, certification, and watchkeeping for seafarers which countries are obliged to meet or exceed. The STCW Convention establishes mandatory levels of competence that must be met by seagoing personnel based on their positions, such as the Master, members of the Deck Department, members of the Engine Department and Radio personnel, as well as establishing watchkeeping requirements.

13 The Safety of the Life at Sea Convention, Chapter V, Regulation 14(2). 14 International Maritime Organization, Resolution A.890 (21), Guidelines for the Application of Principles of Safe Manning, Annex 2, Section 3.1. 15 See The International Convention for the Prevention of Pollution from Ships.

4 (iv) The International Convention on Load Lines

The Deepwater Horizon was in full compliance with the International Convention on Load Lines (Load Line Convention). The Load Line Convention establishes limitations on the draught to which a ship may be loaded, which make a significant contribution to her safety. These limits are given in the form of freeboards, which constitute, besides external weathertight and watertight integrity, the main objective of the Load Line Convention. The regulations take into account the potential hazards present in different zones and different seasons. The technical annex contains several additional safety measures concerning doors, freeing ports, hatchways, and other items. The main purpose of these measures is to ensure the watertight integrity of ships' hulls below the freeboard deck.

(b) Recognized Organizations

The Marshall Islands authorized the American Bureau of Shipping (ABS) as a Reorganized Organization (RO), and ABS conducted annual safety inspections on the Deepwater Horizon for compliance with the 1989 MODU Code, as well as issued certifications to the Deepwater Horizon for compliance with applicable international conventions, including the SOLAS Convention, MARPOL, the STCW Convention, and the Load Line Convention.16

The use of ROs to conduct surveys, inspections, and audits is a long-standing and internationally recognized means of verifying compliance with Flag State and international maritime standards. The SOLAS Convention specifically authorizes the use of ROs to conduct international certification inspections and statutory compliance surveys, subject to oversight by the authorizing Flag State. The International Maritime Organization has established standards for ROs that act on behalf of Flag States with regard to conducting vessel examinations, the issuance of international compliance certificates, and the performance of surveys.17 With respect to MODUs, only organizations that are members of the International Association of Class Societies (IACS) are recognized and authorized by the Marshall Islands to act on its behalf as an RO.18

The Marshall Islands requires self-propelled MODUs, such as the Deepwater Horizon, to comply with the ISM Code and specific Flag State requirements.19 Compliance with the ISM Code is closely monitored and enforced by the Administrator itself and through its appointed ROs and nautical inspectors. Det Norske Veritas (DNV)20 was authorized as an RO by the

16 Republic of the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report, at 24. 17 The U.S. Coast Guard, as the Maritime Administrator for United States flag vessels, also utilizes ROs to perform inspections and surveys on behalf of the United States for U.S. flagged MODUs under its Alternative Compliance Program. See 46 U.S.C. § 3316; 46 C.F.R. Part 8, Subpart D. 18 Republic of the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report, Prologue, at x. 19 Republic of the Marshall Islands Marine Notice 2‐011‐13, available at http://www.register‐ iri.com/forms/upload/MN‐2‐011‐13.pdf. 20 “DNV (Det Norske Veritas) is an independent foundation with the purpose of safeguarding life, property, and the environment. [DNV's] history goes back to 1864, when the foundation was established in Norway to inspect and evaluate the technical condition of Norwegian merchant vessels.” DNV, http://www.dnv.com/moreondnv/profile/about_us/.

5 Marshall Islands to conduct audits and to issue International Safety Management (ISM) and Document of Compliance (DOC) certificates to establish compliance with the ISM Code.21 DNV conducted these functions for the Deepwater Horizon.22

The Deepwater Horizon underwent required U.S. Coast Guard inspections beginning with her arrival in the Gulf of Mexico. In the rig’s most recent inspection, in July 2009, the Deepwater Horizon received no deficiencies.23

The Coast Guard requires foreign flag MODUs operating on the United States OCS to comply with the provisions of 33 C.F.R. Subchapter N. The regulations state that, for purposes of marine safety, foreign flagged MODUs operating on the United States OCS must comply with one of three regulatory schemes, one of which is compliance with the MODU Code.24 The Coast Guard performs annual inspections on foreign flag MODUs operating on the United States OCS to ensure that they meet all applicable United States design, equipment, and operating standards,25 and certifies compliance in accordance with specific guidance for these inspections.26

The MODU Code states that a coastal state (in the case of the Deepwater Horizon, the United States) may impose additional requirements regarding the regulation, surveying and inspection of units engaged in the exploration of natural resources over which the coastal state exercises jurisdiction.27 The United States has enacted the Outer Continental Shelf Lands Act, which authorizes the Secretary of the Interior and the Secretary of the Department in which the U.S. Coast Guard is operating to enforce safety regulations on units operating on the Outer Continental Shelf (OCS).28 Responsibilities for regulation of safety are divided between the Coast Guard and the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) pursuant to a Memorandum of Agreement between the agencies.29

(d) Class Society

The Deepwater Horizon was fully ABS-classed in good standing. ABS was the classification society for statutory, survey, inspection, and certification of the Deepwater Horizon. ABS Class Rules specify detailed requirements as they relate to construction, hull and

6 equipment, general arrangement, structural fire protection, life saving and fire fighting and survey timelines.30

3. Certifications

The Deepwater Horizon was built in accordance with the 1989 MODU Code; the ABS Rules for the Building and Classing of Mobile Offshore Drilling Units, 1997; the Load Line Convention; and U.S. Coast Guard requirements, as the vessel was originally intended to be registered as a U.S. flag vessel.31

ABS classified and certified the Deepwater Horizon as an A1, Column Stabilized Drilling Unit, AMS, ACCU, DPS-3 (the highest rating for dynamically positioned vessels).32 The ABS conducted annual inspections and surveys to ensure the vessel met all requirements as a condition of classification as a Maltese Cross A1 column stabilized drilling unit. These inspections included annual hull, machinery, and safety inspections as noted in the ABS Survey Status Report of April 22, 2010.33 All inspections were current or had been commenced as per ABS rules.34 No major deficiencies were noted and therefore the Deepwater Horizon remained in class as of April 20, 2010 and was considered fit for service.35

On April 20, 2010, the Deepwater Horizon was current on all of its required Flag State statutory surveys and certifications and possessed all requisite international, Marshall Islands, and U.S. Certificates of Compliance.36

The most recent statutory surveys as of April 2010 indicate the following results as they pertain to the rig’s condition.

 Republic of Marshall Islands Report of Safety Inspection issued December 17, 2009 – No deficiencies noted and ship was found to be in compliance with all applicable safety, security, and environmental protection requirements.37

 U.S. Coast Guard Certificate of Compliance issued July 27, 2009 – No deficiencies noted.38

 2007 ISM Code Safety Management Certificate39 and 2009 Transocean ISM Code Document of Compliance.40

4. Manning

On April 20, 2010, the Deepwater Horizon was crewed in accordance with Marshall Islands requirements for safe manning, as established by the SOLAS Convention and international guidelines. All required marine crew positions were filled with mariners holding appropriate credentials and had the appropriate qualifications and competence. Each officer on the Deepwater Horizon held the requisite license, certificate, or document issued by the U.S. Coast Guard and by the Marshall Islands based on their U.S. Coast Guard license, certificate, or document.44

5. Chain of Command

I have concluded that the command structure as established on the Deepwater Horizon was appropriate and in accordance with industry standards45 as well as all applicable laws and regulations.46 I also note the Marshall Islands Deepwater Horizon Marine Casualty Investigation concluded that there is no indication that any confusion regarding the chain of command was a causal factor in the casualty.47

Under the ISM Code, the Master has the overriding authority and the responsibility to make decisions with respect to safety and pollution prevention and to request the company’s

40 Exhibit 953, Det Norske Veritas ISM Code Document of Compliance for Transocean Offshore Deepwater Drilling Inc. 41 American Bureau of Shipping Certificate of Classification, Oct. 19, 2009, TRN‐MDL‐00272528. 42 Underwater Inspection in Lieu of Dry‐Docking (UWILD). The UWILD has been recognized as a valid means to meet the regulatory and MODU Code requirements that a MODU be dry‐docked every five years. The MODU Code specifically states at 1.6.2.5 that "the drydock survey and the inspection of items surveyed at the same time should be such as to ensure that they remain satisfactory for the service for which the unit is intended. An Administration may allow underwater inspections in lieu of a drydock survey provided that they are satisfied that such an inspection is equivalent to a drydock survey." It should be noted that the U.S. Coast Guard also finds that UWILDs are acceptable to meet the dry‐dock requirements for U.S. flag MODUs. 46 C.F.R. § 107.267; Coast Guard Marine Safety Manual, Vol. II, Section B, Chapter 3. 43 ABS Class Survey Report Number MC1722260, TRN‐MDL‐01134503. 44 Republic of the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report, at 58. 45 Deposition of Neil Cramond, 331:13‐332:6. 46 The Marshall Islands, which established the minimum manning standards for the Deepwater Horizon, requires that both a Master and an OIM be on‐board when a dynamically‐positioned MODU or drillship is on location (i.e., drilling or engaged in industrial operations). Schedule DPV to Marshall Islands Marine Notice No. 7‐038‐2, Minimum Safe Manning Requirements for Vessels, http://www.register‐iri.com/forms/upload/MN‐7‐038‐2.pdf. 47 Republic of the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report, at 58.

8 assistance as necessary.48 Pursuant to Marshall Islands requirements, the Master is also in command while the MODU is underway and during all emergencies.49 The Deepwater Horizon Operations Manual clearly states that the Master has overriding authority and responsibility to make decisions with respect to safety and pollution prevention.50 The Station Bill for the Deepwater Horizon clearly establishes the chain of command in an emergency and establishes the Master as the person in charge.51

Pursuant to the Deepwater Horizon Operations Manual, when the vessel was on location and in drilling or industrial operations mode, the Offshore Installation Manager (OIM), who must hold a marine license, is designated the person in charge. On the other hand, when the vessel is in transit, as required by Marshall Islands requirements, the Master is designated the person in charge.52 Nonetheless, regardless of whether the rig was in drilling mode or in transit, the Master retained his overriding authority and was clearly designated as the person in charge during an emergency per the rig Station Bill.

B. Emergency Response and Evacuation

Upon review of Transocean written emergency plans and procedures and the implementation and practice of those procedures onboard, which is verified by safety drill records, I conclude the Deepwater Horizon crew was prepared to properly respond to emergency events. Following a review of witness testimony regarding the speed at which the events unfolded the evening of April 20, 2010, I am convinced no other crew could have been more prepared or capable to effect an evacuation of all remaining survivors given the circumstances. The Deepwater Horizon crew executed their assigned duties flawlessly and with a few exceptions, according to plan. The majority remained calm, even in the midst of an escalating conflagration, to care for the injured and ensure a safe, orderly evacuation off the rig.

1. Sequence of Events on the Evening of April 20, 2010

Given the extreme conditions the Deepwater Horizon crew faced on April 20, 2010, an exact timeline of events is difficult to establish. However, the speed with which the catastrophic events unfolded that evening is undeniable. This is clearly illustrated by testimony from crew members.

Yancy Keplinger testified he was on the bridge when the Captain asked about a high pressure hissing sound.53 When Keplinger heard the sound himself, he immediately looked at a monitor near the control panel that had a feed from a camera on the starboard side of the drill floor.54 It was then that he saw mud spraying out of what he believed was the diverter pipe.55

48 ISM Code § 5.2. 49 Republic of the Marshall Islands Maritime Act (MI‐107) § 811(d). 50 Exhibit 671, Deepwater Horizon Operations Manual § 2.1. 51 Exhibit 1453, Deepwater Horizon Emergency Response Manual, Vol. 1, TRN‐MDL‐00048518. 52 Exhibit 671, Deepwater Horizon Operations Manual § 2.1. 53 Deposition of Yancy Keplinger, 75:14‐76:5. 54 Id. at 76:15‐77:8. 55 Id. at 77:2‐77:13.

9 He ran back to the stability computer and zoomed in on the pipe when he heard and felt an explosion and saw flames.56 The explosion occurred just seconds after he noticed mud spraying out of the pipe.57 Immediately thereafter, combustible and toxic gas alarms were received on the main deck, the drill floor, the shaker room, the sack room, and other places.58 Keplinger went directly to the alarm control panel and started pulling up the alarm pages.59 He tried to silence a couple but realized his efforts were futile.60 He noticed there were alarms for the shaker room, and he called to see if anyone was there.61 The phone rang five or six times with no answer.62 As soon as he hung up the phone, there was a second explosion that blacked out the rig.63

Paul Meinhart, who was on watch in the engine control room, testified he saw a blue light on the alarm panel in the engine control room, indicating the presence of gas.64 Within seconds of seeing the blue light, he heard an announcement from the bridge advising the Damon Bankston, a vessel working with the rig, to move away from the rig because of a well control situation.65 Very shortly thereafter, other gas alarms went off.66 Meinhart then recalls that, within seconds, the rig went dark.67 Then, within 10 or 15 seconds of the rig going dark, there was an explosion.68 Within another 10-15 seconds, there was a second explosion.69

Craig Breland testified the time between the first explosion and the second explosion was “[m]aybe ten seconds, maybe less than that.”70 Then “right after it happened, the fire alarm went off” and “over the PA it said this is not a drill, this is not a drill. Fire on the rig.”71 After another “[m]aybe 10, 15 seconds” or “[m]aybe 30,” “the abandon rig alarm went off and over the PA system.72 Breland estimates the total time between the first explosion and the abandon alarm was between thirty seconds and a minute.73

As this testimony illustrates, the personnel on the bridge the evening of April 20, 2010 quickly responded. Within seconds of the initial well blowout, the bridge crew instructed the Damon Bankston to move away from the rig. Immediately following the explosions, they sounded the general alarm and made PA announcements instructing the crew to muster for

10 evacuation. By utilizing both the general alarm and PA announcements, the crew was timely alerted of the emergency situation and guided to the forward lifeboats.74

I believe it is very likely the bridge crew’s quick decisions and clear instructions led to a safe and successful evacuation of the Deepwater Horizon.

2. Deepwater Horizon Emergency Policies and Procedures

(a) Emergency Response Plans

The Deepwater Horizon Emergency Response Manual provided the crew with necessary guidance on how to conduct themselves during the events of April 20, 2010. The Manual includes an Abandon Unit/Evacuation Plan, which adequately outlines the procedures for abandonment.75 The Plan summarizes the proper protocol for launching lifeboats.76 It also defines the roles of the Deepwater Horizon crew members during an evacuation.77 According to the Plan, all personnel are instructed to don life preservers and immediately head to their assigned lifeboat upon hearing the Abandon Ship Alarm.78 As discussed in detail below, the rig crew who survived the initial blast complied with these procedures.

(b) Emergency Response Drills

Emergency response drills were conducted aboard the Deepwater Horizon in accordance with the Transocean Health and Safety Policies and Procedures Manual. The manual specifies that Fire and Abandon emergency response drills must be conducted on installations at least weekly.79 According to safety drill reports from the Deepwater Horizon, the following Fire and Abandon drills were conducted during April 2010:80

The last Fire drill was conducted two days prior to the incident; the last Abandon Ship drill was conducted three days prior to the incident. The safety drill reports indicate the crew mustered in a timely manner in response to both drills.81 During the Abandon Ship drill, the lifeboats were lowered as part of the weekly inspection.82 Similar drills were conducted on the rig in 2009 and January, February, and March 2010.83

Sufficient lifesaving appliances were available to the Deepwater Horizon crew on the evening of April 20, 2010. The Deepwater Horizon had a total of four lifeboats with the primary muster location at Lifeboats Numbers 1 and 2 located forward on the rig. Lifeboats Numbers 3 and 4 were ‘alternate’ muster locations and located aft on the rig.84 Each lifeboat was certified to carry 73 people.85 Thus, each muster station, ‘primary’ (forward) or ‘alternative’ (aft) had a total lifeboat capacity of 146 people, well above the 126 individuals onboard the rig. In addition to four lifeboats, the Deepwater Horizon was equipped with six 25-man life rafts.86 Three were located forward by the lifeboat deck, and three were located aft.87

12 3. Effectiveness of Muster and Evacuation

Crew members and visitors alike were schooled in the muster process. The rig Station Bill readily identified the crew’s muster stations.88 To ensure the Station Bill was easily accessible by all crew members, the Station Bill was conspicuously displayed throughout the rig in accordance with the 1989 MODU Code.89 Moreover, all new crew members and visitors that arrived on the Deepwater Horizon reviewed the Station Bill as part of the rig orientation.90 Crew members also were required to report to their respective muster stations during weekly emergency response drills.91 With these policies and procedures in place, the Deepwater Horizon crew was fully prepared for the muster process on the evening of April 20, 2010.

After attempting to muster in accordance with the Station Bill and instructions from the bridge, all 115 survivors of the initial blast abandoned the rig. Four persons apparently panicked and jumped into the water before lifeboats were launched.92 It is a true testament to the crew’s training and safety culture that only these individuals jumped prior to any lifesaving appliance being launched.

Seven members disembarked the Deepwater Horizon via one life raft. These seven individuals arrived at the forward lifeboat stations after the two lifeboats were launched. Their delayed arrival was due mainly to their individual efforts to help other persons, continue emergency announcements, and attempt to start emergency systems.

Chad Murray, the Chief Electrician, had to take several alternate routes to reach the muster area. He assisted an injured crew member to the medic. At the lifeboats, he helped severely injured crew members successfully evacuate the rig before boarding the life raft.93

Dave Young, the Chief Mate, immediately reported to the bridge after the first explosion. He ensured the general alarm was sounded and reported to his fire fighting station before proceeding to the lifeboats.94

Wyman Wheeler, a Toolpusher, was injured, which delayed his arrival at the lifeboats.95

Stanley Carden, Jr., the Electrical Supervisor, assisted an injured crew member to the medic before helping Wyman Wheeler, who was also injured, to the forward lifeboat station.96

Andrea Fleytas, the Dynamic Positioning Officer on watch at the time of the explosions, stayed on the bridge to make emergency radio calls. She ultimately made her way to a life raft.97

Miles Randy Ezell, the Senior Toolpusher, aided others in helping two injured crew members, Buddy Trahan and Wyman Wheeler. He helped load Wyman Wheeler into the raft, before boarding the raft himself.98

Steve Bertone, the Chief Engineer, guided other crew members to forward spiral staircases and out to muster areas. Bertone, along with Mike Williams and Paul Meinhart, attempted to start the standby generator. He also aided in preparing the life raft to deploy and assisted loading severely injured personnel into the raft, before also boarding.99

The last four crew members to depart the Deepwater Horizon were Captain Curt Kuchta, the Master; Mike Williams, the Chief Electronic Technician; Paul Meinhart, a Motorman; and, Yancy Keplinger, the Senior Dynamic Positioning Officer on watch at the time of the explosions. These four performed emergency response activities, such as launching life rafts, attempting to start the emergency generator and other activities, as long as possible before being forced to jump from the rig due to the growing intensity of the fire.100

Although nothing could fully prepare anyone for the unprecedented events that transpired on April 20, 2010, the Abandon Unit/Evacuation Plan, the Station Bill, and the emergency response drills ensured the entire rig crew was prepared to respond in an emergency situation. The crew members themselves also were integral to the success of the muster and evacuation. Normal evacuation routes were blocked by debris and damage to the rig from the initial explosions. Throughout the evacuation, the rig remained engulfed in flames and the conditions aboard the continued to deteriorate with every passing second. Yet, certain individuals managed to assist those that were injured make their way to the awaiting lifeboats and life rafts. Despite

14 unimaginable circumstances, all 115 crew members who survived the initial explosions were able to safely evacuate to the Damon Bankston.

C. Safety Culture

I have reviewed documents and testimony regarding Transocean’s safety policies and programs and the implementation of those programs. I have also reviewed documentary evidence and testimony regarding company attitudes toward Transocean’s safety culture, from upper management to the rig crews. Based on this review, I conclude that the Deepwater Horizon crew demonstrated a strong safety culture, which was integrated into the daily operational activities performed onboard the rig. Further, I have found no evidence that any lack of commitment to safety by the crew of the Deepwater Horizon could have contributed to the events of April 20, 2010.

1. Transocean Safety Programs

Transocean implemented several programs and processes to ensure all activities performed on its MODUs and offshore rigs were safely conducted. These processes were effectively implemented on the Deepwater Horizon and played a significant role in supplementing the rig’s commitment to safety.

(a) START Process

The Transoean START Process is used to observe and monitor work practices, THINK plans, and workplace conditions.101 Employees are empowered to observe tasks and work areas for both safe and unsafe behaviors and conditions. The policy likewise empowers employees to monitor themselves and others to ensure the safe execution of THINK plans by interrupting and correcting unsafe behaviors, conditions, and unplanned changes.102 Goals of the START Process include increasing personnel's ability to recognize and respond to hazards, promoting accountability for maintaining a safe workplace, and obtaining commitment among co-workers to repeat safe behavior.103 Daily START observations are recorded on START Cards.104 The Card captures observations of behaviors, personnel positioning, personal protective equipment, tools and equipment, conditions (e.g. weather, lighting potential, condition of work area), and environmental concerns.105

101 Exhibit 1449, Transocean Health and Safety Policies and Procedures Manual, Section 4, Subsection 5.1 (TRN‐ MDL‐00046738). 102 Id. 103 Id. 104 Id. 105 Id. at Figure A.

15 (b) THINK Planning Process

The Transocean THINK Planning Process sets forth guidelines and procedures for personnel to confirm proper risk controls are in place prior to beginning all tasks.106 The purpose of such a policy is to ensure hazards are identified and risks are effectively managed and controlled at all times.107 The steps in the process are (1) Plan; (2) Inspect; (3) Identify; (4) Communicate; and (5) Control. The THINK Planning Process was utilized on the Deepwater Horizon and, indeed, expected by leadership on the rig.108

On each of its rigs, Transocean implements a program called “Time Out for Safety” (TOFS). During rig operations, everyone has the authority, indeed an obligation, to stop work if an activity poses a safety risk of any magnitude. The exercise of this authority is referred to as a TOFS.109 To illustrate, Mark Hay, a Transocean Subsea Supervisor, noted that Transocean as a corporation and the Deepwater Horizon crew in particular emphasized the TOFS program. He testified that: “Any time you see[] somebody working unsafe[ly] or if you really didn't know what they w[ere] doing, . . . we []forced everybody to take the time out for safety, discuss it, talk about it, and start the job over. In the middle of a job if—if you thought there was a different way or better way, we could take a timeout for safety.”110 The Deepwater Horizon regularly utilized the TOFS program as a safety tool aboard the rig.111

Transocean management encourages employees to utilize this authority and recognizes those who call a TOFS through the “I Made a Difference” campaign. As described by Gerald Canducci, QHSE Manager for North America, the “I Made a Difference” campaign starts with a documented time-out for safety that occurred on a rig.112 The corporate office “choose[s] one that is noteworthy and they distribute it throughout the company saying, trying to show people that calling a time-out for safety is nothing to be frightened to do. We encourage it every day, all the time.”113

2. Orientations, Safety Meetings, and Safety Programs

The importance of creating a safe working environment and conducting safe operations was also reinforced through comprehensive orientations, daily and weekly safety meetings, and safety programs implemented on the Deepwater Horizon. Additionally, the crew conducted numerous drills, including: fire, evacuation, and muster drills, many of which are addressed in detail in the Emergency Response and Evacuation section of this report.

16 (a) Orientations

When crew or visitors arrived at the rig, they were required to participate in a comprehensive orientation program.114 The orientation incorporated safety videos and briefing, discussion of evacuation procedures, identification of required personal protective equipment, and a rig tour, which included identification of assigned lifeboat stations.115 Additionally, the Station Bill was reviewed, which outlines individual assignments in the event of an emergency.116 The Deepwater Horizon crew and those who visited the rig consistently testified the orientation was thorough, extensive, professionally conducted,117 and contributed to the successful evacuation of the rig.118

(b) Safety Meetings

Each day on the Deepwater Horizon, two safety meetings were conducted: one at each tour change. Additionally, there were once weekly rig-wide safety meetings and once weekly departmental safety meetings.119 Accordingly, in a given week, each crew member participated in approximately eight safety meetings. In addition to Transocean employees, BP crew members and third party contractors also participated. Records of the occurrence of these meetings are evidenced in IADC Daily Drilling reports.120

Testimony from the crew indicates that the meetings were well-attended and taken seriously.121 The content of the meetings varied and included corporate and regulatory safety bulletins, lessons learned, upcoming jobs, good safety practices, and safety planning.122

3. Attitudes Toward Safety

Transocean management emphasized and encouraged safety, and this philosophy was communicated through the organization and effectively implemented at all levels.123

(a) Shore-Based Management

Transocean management’s support for safety is embodied in the Transocean Safety Vision: “[Transocean’s] operations will be conducted in an incident-free workplace—all the time, everywhere.”124 Transocean management worked to foster an effective safety management culture and ensure that the company’s safety vision resonated through to the crew members aboard its rigs. By way of example, the Deepwater Horizon Rig Manager Performance began his daily meeting with the rig crew by discussing safety as the first priority and item of business.125 But, perhaps the best indication of management’s dedication to safety is the rig crew members themselves. Based on surveys regarding the rig’s safety culture, 100% of the crew members believed they understood the safety procedures and hazards of their jobs because of the training and support they received.126 97.6% of survey participants believed that Line Managers listened and acted on the workforce’s safety concerns.127 An anonymous responder to the survey referred to the Rig Manager as “a very strong safety leader.”128

(b) Rig Management

The rig management for the Deepwater Horizon supported a robust safety culture aboard the rig, and the crew aboard the Deepwater Horizon viewed the rig-based management in a very positive light.129 David Young, Chief Mate on the Deepwater Horizon, referred to the rig’s safety as “top-down…it really worked in both directions…the Supervisors [were] there [to] teach everybody about the expectations. And at the same time…the guys at the lower end were able to

123 See Exhibit 3818, Lloyd’s Register Safety Management and Safety Culture/Climate Summary Review for Deepwater Horizon at 21 (TRN‐MDL‐00119612) (finding that nearly all survey participants believed that Transocean felt that their safety was important to them); id. (referring to anonymous crew statement “[Leadership is] “visible, approachable, and safety oriented.”); id. at 8 (97.6% of participants were encouraged to raise ideas and suggest safer ways to do things). 124 Exhibit 1449, Transocean Health and Safety Policies and Procedures Manual, Section 1, Subsection 2 (Dec. 15, 2009). 125 Deposition of Paul Johnson, Vol. 1, 47:9‐48:23. 126 See Exhibit 3818, Lloyd’s Register Safety Management and Safety Culture/Climate Summary Review for Deepwater Horizon at 8 (TRN‐MDL‐00119619). 127 Id. 128 Id. at 12. 129 Id. at 20. In addition, Doug Brown said of Jimmy Harrell, the Offshore Installation Manager (OIM), “with Jimmy, it was “the safe way or no way.” Deposition of Doug Brown, 298:3‐6. Murry Sepulvado concurred with Doug Brown’s assessment of Jimmy Harrell, attesting he “was always on top of safety and safety was always number one.” Deposition of Murry Sepulvado, 531:2‐3.

18 stop jobs [and] bring up safety issues that would be addressed by the upper level management.”130

The crew’s commitment to safety as implemented by the rig’s management also was recognized by BP and other third parties onboard the rig. For example, Patrick O’Bryan, BP’s Vice President of Drilling and Completions for the Gulf of Mexico, Deepwater, characterized the Deepwater Horizon as the best-performing rig in BP's fleet—in terms of both drilling performance and safety.131 Murray Sepulvado, one of the BP Well Site Leaders, described Transocean's culture as “safety first, environment, and then the task at hand, and everybody supported that.”132 Ronnie Sepulvado, another BP Well Site Leader, testified the Deepwater Horizon crew were “good people, good workers and good safety people.”133 Other BP employees echoed this praise of Transocean’s safety culture, describing the rig as “very safety- oriented,” a “leader[] of the pack,”134 and managed by safety conscious individuals.135

Bill Sannan, Transocean General Manager – North America, expressed that “the safety performance of the Deepwater Horizon was very good.”136 Members of the rig’s subsea team also confirmed that “safety was paramount on the Horizon” and that the Deepwater Horizon crew placed an emphasis on safety.137 Transocean Floorhand Caleb Holloway also stressed that safety was prioritized on the rig, where the importance of maintaining a safe working environment was underscored.138 Likewise, Transocean Roustabouts Nick Watson and Dustin Johnson explained, respectively, that the safety policies and procedures were strictly enforced,139 and that the rig put safety first, twenty-four hours a day, seven days a week.140 Brent Mansfield, a Transocean First Assistant Engineer, concurred, noting that rig management, supported and encouraged time outs for safety.141 Caleb Holloway, a Transocean Floorhand, reiterated that everyone had the right to call a TOFS, and personally he felt comfortable calling a TOFS if he perceived a situation to be potentially hazardous. Rig management supported Holloway when he used the timeout for safety procedure, and Holloway was unaware of any Transocean employee

19 being reprimanded for calling a TOFS.142 David Hackney, a Master aboard the Deepwater Horizon, described the Deepwater Horizon safety culture as strong and effective.143

The testimony of third-party subcontractor employees confirms this view. To illustrate, Kelly Gray of Sperry Sun observed that the rig’s performance was a testament to the crew’s “commitment to safety,”144 and a Cameron hand, William LeNormand, echoed the opinion that safety was a priority on Transocean rigs.145

I also note that various third party representatives and regulatory inspectors had been aboard the Deepwater Horizon to conduct inspections. These individuals are experienced inspectors and visit and inspect multiple rigs in the course of their day-to-day work. As part of these inspections, one facet, in addition to regulatory compliance, would be to assess safety culture based on observed safety practices. While they would not have had an intimate knowledge of the Deepwater Horizon’s safety culture, they would have been in a good position to compare their experiences aboard the Deepwater Horizon with their experiences aboard other rigs and subjectively form an opinion. These individuals confirmed that Transocean was “serious about safety management,”146 the rig’s safety culture was “safety conscious,”147 and the rig was committed to regulatory compliance.148

In conclusion, my review and analysis leads me to conclude that the safety programs developed by Transocean and implemented by the safety-conscious crew onboard the Deepwater Horizon, combined to create a strong and effective safety culture on the rig. My conclusions are supported by the testimony of Transocean, BP, and subcontractor employees, as well as that of the U.S., the Flag State, and independent inspectors who inspected the rig and observed operations onboard.

D. Vessel Integrity

Based on a review of audits and inspections, depositions, and testimony of key personnel and various reports, the Deepwater Horizon was fit for the service intended on April 20, 2010. Since delivery of the Deepwater Horizon in 2001, the rig has undergone continuous inspections, surveys, and audits conducted by the recognized Flag State, Coastal State, Classification Societies, BP, and external auditors on behalf of Transocean.

142 See Deposition of Caleb Holloway, Vol. 1, 94:18‐95:20, 150:15‐151:12; see also Deposition of Nick Watson, Vol. 1, 168:16‐169:12. 143 Deposition of David Hackney, Vol. 1, 174:24‐175:2 (describing the Deepwater Horizon safety culture as strong and effective). 144 Deposition of Kelly Gray, Vol. 2, 525:20‐526:4. 145 Deposition of William LeNormand, Vol. 2, 126:8‐12. 146 See Deposition of David McKay, Vol. 1, 100:23‐101:22; see also Deposition of Alan Schneider, Vol. 1, 33:11‐ 34:10. 147 Deposition of Eric Neal, Vol. 1, 131:7‐132:6; Deposition of Alan Schneider, Vol. 1, 370:22‐372:10 (discussing the sophistication and thoroughness of the Deepwater Horizon’s rig safety orientation). 148 Deposition of Eric Neal, Vol. 1, 131:7‐132:6; Deposition of William Hainey, 184:25‐188:12, 278:7‐12; U.S. Coast Guard Certificate of Compliance, Jul. 27, 2009, TRN‐MDL‐01101583‐1585.

20 While mandated statutory surveys and inspections assess the rig against statutory standards, the Deepwater Horizon was also subjected to BP audits and voluntary ModuSpec USA, Inc. (ModuSpec) audits that went well beyond the basic statutory regime and were designed to be a much more rigorous, inward-focused self analysis that incorporated not only statutory compliance, but compliance with more stringent company goals.

In view of the Deepwater Horizon’s documented compliance with statutory requirements, and based on the corrective actions taken to rectify the results of the 2009 BP Marine Assurance Audit149 and the purpose of ModuSpec’s April 2010 Rig Condition Assessment Survey as discussed below, I am of the opinion and conclude that the Deepwater Horizon was fit for the service intended as of April 20, 2010.

1. Compliance with Flag, Port State and Classification Society

The Deepwater Horizon was current on all its required Flag State surveys and certifications and possessed all required international and Flag State documents and certificates with no outstanding deficiencies. Additionally, the rig, operating in U.S. waters, held a valid and current U.S. Coast Guard Certificate of Compliance.150 Of specific note, William Haynie, principal surveyor for ABS, concluded that at no point in time did ABS uncover any deficiency or evidence that Transocean was not keeping the Deepwater Horizon in compliance with ABS Class Rules. He further attested that at the time of the explosion on April 20, 2010, the rig was considered to be “in class.”151

2. Audits Conducted Beyond the Statutory Requirements

In addition to the mandated surveys and inspections to ensure statutory compliance, BP and Transocean routinely conducted detailed audits and surveys above and beyond those required by regulation to specifically assess the vessel’s overall condition against more stringent company requirements. BP initially conducted an Integrated Acceptance Audit in 2001.152 Following this audit, BP conducted Technical Rig and/or Marine Assurance audits on January 17-21, 2005,153 January 15-19, 2008,154 and September 13-17, 2009.155 Additionally, Transocean, on its own accord, contracted with a third party, ModuSpec, to conduct a comprehensive rig condition assessment from April 1-12, 2010. The closeout of the BP 2009 Marine Assurance Audit156 and the ModuSpec Rig Condition Assessment of April 1-12, 2010157 provides the most accurate picture of the rig’s condition as of April 20, 2010.

21 (a) BP Rig and Marine Assurance Audit of September 13-17, 2009

As part of a planned maintenance schedule, the Deepwater Horizon commenced an out of service period on August 31, 2009 to conduct an Underwater Survey in Lieu of Drydocking (UWILD) survey and dynamic positioning system upgrades.158 In conjunction with the UWILD survey, BP additionally conducted a rig and marine assurance audit to determine if the vessel was seaworthy and fit for its duty as a drilling rig.159 As part of the audit process, BP used their Common Marine Inspection Document (CMID) MODU Annex as a template to conduct the audit. The CMID is considered to be a common marine auditing standard based upon guidance issued by the International Marine Contractor’s Association (IMCA).160 All noted discrepancies identified were tracked on Audit Report Action Sheets (ARAS) and included recommendations on the time frames for resolution of individual items. These discrepancies and recommendations were presented to Transocean for review and resolution.161

The ARAS identified 70 discrepancies that were considered marine-related. Each item was categorized on a spreadsheet by reference number and CMID reference number, with the description of the discrepancy, targeted completion date to be resolved, corrective action plan, and BP acceptance (sign off) of the item when completed. The listed discrepancies had various target completion dates depending upon the severity of the deficiency as determined by BP.162

Of particular note, certain discrepancies were deemed critical enough to require resolution before the Deepwater Horizon could commence operations. These discrepancies were resolved by Transocean and the rig was cleared by BP to begin drilling operations on September 22, 2009.163 Neil Cramond, the BP’s Gulf of Mexico SPU Marine Authority, who was responsible for overseeing BP’s marine program, reached the conclusion that, as a result of the mitigation plan that was put into place to address remaining discrepancies and based on those conditions that were rectified, the Deepwater Horizon did not pose a marine safety risk as of September 22, 2009.164 However, Paul Johnson, Transocean’s Rig Manager for the Deepwater Horizon, despite having authority from BP to resume drilling operations, stated he personally held up the rig from going back to work for an additional 5 to 6 days until issues with the pipe rack system were resolved.165

When the rig returned to service, the Deepwater Horizon crew and Transocean management worked to rectify the deficiencies identified in the audit based on the mitigation plan approved by BP. A good working relationship was evident between BP’s audit review team and the Transocean crew responsible for fixing all discrepancies. Brett Cocales, BP Operations Engineer, believed that the crew of the Deepwater Horizon deserved to be commended for

Upon review of BP’s CMID audit work list, 63 of 70 deficiencies were signed off as completed by March 29, 2010.168 The remaining 7 items were awaiting parts or to be sent ashore for repair and these remedial actions were approved by BP.169 Of significant note, BP’s Marine Authority, Neil Cramond, was not aware of any conditions on the Deepwater Horizon through April 2010 that would give rise to safety concerns.170 This was confirmed by other BP personnel.171 Cramond also was not aware of any items from the 2009 audit that remained outstanding that were directly related to the April 20, 2010 incident onboard the Deepwater Horizon.172 Additionally, Mark Bly, BP Investigative Team Leader for the BP internal investigation, considered the Deepwater Horizon to be one of the best rigs in the BP fleet.173

(b) ModuSpec Audit Report of the Deepwater Horizon

Transocean contracted ModuSpec to complete a condition assessment of the primary assets of the rig including drilling equipment, mud system, well control equipment, marine equipment, hull, structure, power plant, electrical equipment and safety equipment. A Rig Condition Assessment was conducted on the Deepwater Horizon by ModuSpec during the period from April 1–12, 2010.174

According to Peter Sierdsma, President of ModuSpec, the survey conducted for Transocean was a voluntary effort over and above those surveys required by various laws and regulations that apply to MODUs.175 ModuSpec’s survey was intrusive, meaning that the equipment was opened for inspection.176 The Rig Condition Assessment was specific to Transocean and followed Transocean guidelines and good oilfield practices based on industry standards.177 The goal was to provide Transocean with a true, unbiased assessment of the vessel’s condition,178 and to determine the effectiveness of, and the unit’s compliance with, Transocean’s maintenance and management system.179 ModuSpec’s Rig Condition Assessment

23 concluded that the rig appeared to be in fair condition for marine integrity and that the hull was in good condition.180

Alan Schneider, Technical Supervisor for ModuSpec and the lead surveyor on the April 2010 survey, stated that after ten days of being on the Deepwater Horizon, he felt there was no condition that provided an imminent danger that warranted a shutdown of the rig.181 While there were numerous findings in the report that required additional maintenance typical of a rig this age, ModuSpec’s Marine Equipment Rating (MER), a system by which the Deepwater Horizon is compared to other MODUs operating in the Gulf of Mexico and worldwide, was considered favorable by Schneider.182

3. Structural Fire Protection, MODU Structure and Stability

Since the Deepwater Horizon was designed to comply with the 1989 MODU Code, the rig met regulatory requirements related to the construction requirements for structural fire protection (SFP). The design philosophy behind SFP is the segregation of spaces onboard the rig by relative fire hazard potential and time barriers to prevent spread of fire and smoke both vertically and horizontally by means of bulkhead integrity and insulation value. Separation of spaces by A, B, or C class bulkheads on the Deepwater Horizon were appropriately insulated where required.183

In addition to passive (non-combustible) space segregation, the rig was outfitted with active fire protection capability, including sprinkler systems and failsafe fire dampers. Remote activated fire dampers are designed to close in the event of fire or gas detection.184 All 26 remote operated dampers passed BP’s September 2009 audit and were signed off as operational on October 20, 2009.185 Additionally, the rig maintained an ABS approved Fire Control Plan.186 As noted by the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report, SFP measures were in compliance with regulatory requirements. The report asserts that the use of non-combustible construction and SFP allowed the unit to remain structurally sound long enough for the evacuation of the individuals onboard the unit.187

Furthermore, in September 2009, the ABS, on behalf of the Marshall Islands and for purposes of maintaining class, conducted an UWILD survey to determine the structural condition and integrity of the Deepwater Horizon. This included close-up visual examination and non-

24 destructive testing of major structural components and critical structural areas.188 The UWILD survey was completed with no deficiencies.189

With respect to MODU structure and stability, the rig withstood the forces of the explosion and resulting fire, and although subjected to intense heat and dynamic loading, provided a sufficiently stable and protected platform to facilitate the evacuation of 115 individuals. The Deepwater Horizon sank approximately 36 hours after the first explosion. The explosions likely caused structural damage that led initially to the listing of the rig to starboard,190 and ultimately the extreme heat from the fire caused bending, breaking, and warping that would result in structural failure.191

E. Fire and Gas Detection and Alarm Systems

Based on my review of alarm design documents, maintenance documents, and testimony, I conclude the Deepwater Horizon’s fire and gas detection and alarm system (the “Alarm System”) was designed, installed, and maintained in accordance with relevant rules, engineering principles of hierarchy, and common industry best practices. As explained below, the system was fully functional and worked as designed on April 20, 2010.

1. Components of Alarm System

The Deepwater Horizon Alarm System provided early and reliable detection of fire and gas hazards, wherever such events were likely to occur, and alerted personnel and initiated protective actions automatically or manually upon operator’s activation.192 The system processed input signals from field mounted detectors and manual fire alarm stations.193 The protection system was designed to initiate certain shutdown actions via the Emergency Shutdown System (ESD).194

The Deepwater Horizon Alarm System included over 500 automatic sensors and manual fire alarm stations located throughout the rig.195 Specifically, the fire detection system consisted of manual alarm stations and heat, smoke, and flame detectors.196 The gas detection system 197 consisted of combustible and toxic (H2S) detectors. [see Figures 1-5]

The Alarm System also included a fully redundant communications network and system of electronic controllers designed so that the system would continue to operate upon the potential failure of an individual component.198

2. Monitoring of Fire and Gas Detection System

The Alarm System could be controlled and monitored at different locations on the Deepwater Horizon.199 [see Figure 6] Control panels were located on the bridge, in the engine control room (ECR) and at the driller’s work station (DWS).200

30 Figure 6

On the bridge, dynamic position operators (DPOs) monitored the Alarm System 24 hours a day.201 Other members of the crew also could monitor and operate the system from the ECR and DWS as needed.202 The ECR was designated as a secondary response point in the event the bridge was unavailable.203 All personnel on the rig were authorized to activate the fire alarm and notify the bridge upon detecting a fire or other hazard.204

31 Each of the control panels provided the real-time status of the Alarm System and was capable of starting the fire pumps.205 When an alarm was triggered on the Deepwater Horizon, the Alarm System would activate audible and visual alarms at the bridge, the ECR, and the DWS.206 Notably, these alarms were integrated with the ESD alarm panel, which would also activate at the bridge, ECR, and DWS.207

3. Compliance with Applicable Regulations

The Deepwater Horizon Alarm System was designed and installed to comply with applicable regulations.208 This compliance was verified independently by the American Bureau of Shipping (ABS) on behalf of the Flag State and for Class purposes.209 In addition, compliance was maintained and confirmed during Mobile Offshore Drilling Unit Certificate surveys, and through periodic coastal state inspections by the Minerals Management Service (MMS) and the U.S. Coast Guard.210

4. Configuration of General Alarm

The Deepwater Horizon was equipped with a “General Alarm,” which was intended to alert all persons onboard of an emergency situation, including but not limited to collision, fire, presence of gas, man overboard, or abandon rig.211 The alert was accomplished through a number of sound producing devices and visual lights which could be heard and/or seen throughout the entire rig.212 The General Alarm on the Deepwater Horizon was configured for manual activation via manual call points in accordance with U.S. Coast Guard, the 1989 MODU Code, and the SOLAS Convention requirements.213 There are two primary reasons for the manual activation requirement. First, it is well-documented that false alarms can lead to what is known as “alarm fatigue.” Smoke detectors may falsely identify small particles (e.g., soot, dust, cement, steam, water vapor, and sand particles) as smoke and are prone to triggering frequent alarms due to their exposure to the elements. If these false alarms were to sound regularly, as has been the case when marine alarm systems are set in automatic mode, crew responsiveness would likely decline. Crew members experiencing alarm fatigue begin to treat all alarms as nuisance alarms. Second, regular but false general alarms would interrupt crew sleep patterns

205 See Exhibit 1118, Deepwater Horizon Safety System Design Philosophy, Aug. 23, 2000; Exhibit 1102, Kongsberg Safety Philosophy: ESD, PSD, and F&G, at 39. 206 See Deposition of Yancy Keplinger, 62:9‐63:19; Exhibit 1111, Deepwater Horizon F&G System Manual, Feb. 15, 2001, at 18. 207 Exhibit 1118, Deepwater Horizon Safety System Design Philosophy Aug. 23, 2000, at 2. 208 Id.; Republic of the Marshall Islands Deepwater Horizon Marine Casualty Investigation Report Aug. 17, 2011, at 9. 209 See Exhibit 1118, Deepwater Horizon Safety System Design Philosophy, Aug. 23, 2000, at 1. 210 See Exhibit 3075, List of MODU Safety Certificates for Panama and Marshall Islands; see also Regulatory Compliance Section. 211 See Exhibit 597, Deepwater Horizon Emergency Response Manual, Section 4.1, Mar. 31, 2006; Exhibit 1118, Deepwater Horizon Safety System Design Philosophy, Aug. 23, 2000. 212 See Exhibit 1118, Deepwater Horizon Safety System Design Philosophy Aug. 23, 2000, at 11‐12. 213 See Exhibit 1119, U.S. Coast Guard Navigation and Vessel Inspection Circular No. 2‐89, Section 5.2, Aug. 14, 1989.

32 and lead to crew fatigue, which would increase accidents and human error. The manual activation system prevents these fatigue problems and ensures the crew properly responds to legitimate alarms.

Even when configured for manual activation, the General Alarm automatically would activate if an alarm went unacknowledged for two minutes.214 This arrangement was consistent with the U.S. Coast Guard, 1989 MODU Code, and the SOLAS Convention requirements.215

5. Emergency Shutdown System

Because of the risks posed by the rig’s loss of power, the ESD system was properly designed to require manual rather than automatic activation to shut down ventilation in the engine generator rooms.216 The Deepwater Horizon’s fire and gas detection system was designed to initiate shutdown actions via the ESD System.217 Examples of shutdown actions are the closure of fire dampers, the stopping or starting of ventilation fans, and the closure of fire doors.218 Shutdown actions were able to be initiated automatically, or manually from the Central Control Room (CCR), Driller’s Workstation (DWS), or Engine Control Room (ECR).219 Because the Deepwater Horizon was a dynamically positioned (DP) vessel, manual activation of the ESD was required to shut down ventilation to the rig’s engine generator rooms.220 A DP vessel requires power for its station keeping system and thrusters to maintain its position.221 Without power, the rig would lose its ability to stay in position and thus would drift off location. A powerless, drifting rig is a serious hazard to personnel onboard, as well as to those on nearby vessels. It can also have significant environmental consequences if the drifting rig pulls against the BOP through the riser (e.g., breaking the riser, or topping or damaging the BOP).

6. Maintenance and Condition of Alarm System

The Deepwater Horizon’s Alarm System was fully functional and properly maintained as of April 20, 2010.222 Beginning with its initial installation and commissioning, the system was regularly tested and rigorously maintained.223 The condition and maintenance level of the Alarm

33 System was reviewed and found acceptable by BP’s own marine assurance auditor, Angel Rodriguez, as well as ModuSpec auditors only days prior to April 20, 2010. No sensors were inhibited as of Angel Rodriguez’s March 29, 2010 visit to the rig or the ModuSpec review during April 1-12, 2010.224 Even if a few sensors were inhibited between April 12 and April 20, 2010, this would not have degraded or jeopardized the reliability of the system as a whole due to the sheer volume and redundancy of sensors.225

Like the fire and gas detection system, the ESD system was tested, maintained, and fully functional as of April 20, 2010.226 The condition and maintenance level of the ESD system was reviewed and found acceptable by BP’s own marine assurance auditor.227 ESD levels were clearly articulated in the design, and the interfaces with the Safety System Cause and Effect Matrix were understood, tested, and maintained.

7. Alarm Procedures Followed on April 20, 2010

The Deepwater Horizon Alarm System worked as designed on the night of April 20, 2010. The detection system detected the presence of hydrocarbon gases in various areas around the rig and alerted the bridge team and personnel in the engine control room.228 The bridge followed the prescribed operating procedure for responding to an alarm and began calling areas where gas was detected, timely sounded the general alarm, and made public address announcements ordering the drill crew to emergency muster stations.229 Unfortunately, the evidence suggests the Deepwater Horizon experienced a catastrophic blowout that overwhelmed the various preventative systems in place.

8. Fire Suppression System

The Deepwater Horizon was equipped with a fixed CO2 fire suppression system. The CO2 fire suppression system protected, among other areas, the control rooms, engine rooms, and electrical equipment rooms; it employed CO2 gas as the active fire extinguishing agent (deployed as a total flooding system).230 Additionally, the generators and thruster motors, being totally- 231 enclosed, water-cooled designs, included CO2 machine enclosure flooding systems. These fixed CO2 fire suppression systems for total flooding were connected to and monitored by the 232 fire and gas system to assure that the CO2 systems were as safe and effective as possible.

Additionally, the Deepwater Horizon was equipped with an automatic sprinkler system in the accommodations block and a separate, manually activated structural fire protection deluge

34 system to protect the drill floor support structure within the moon pool area.233 The sprinkler system and deluge system included pressure or flow monitoring switches connected to the fire and gas system to indicate any time either of these systems had been activated and to automatically sound alarms and shutdown ventilation in the affected area if the sprinkler system is activated.234

These fire suppression systems on the Deepwater Horizon were fully functional and properly maintained as of April 2010.235 As of the last reported date of inspection, the system operated as designed.236

9. The BOP-Driller’s Control Panel

Even in the “bypass” mode, the driller’s control panel constantly was purged and pressured with air.237 Also, because the panel is located in the Driller’s Workstation (DWS), which itself was a purged system, any isolated purging of the BOP panel was redundant. Accordingly, the panel was deemed safe to operate and had no effect on the driller’s ability to control or operate the BOP.

The DWS [see Figure 7, “Driller’s Workstation”] was located within the perimeter of the derrick, a “Zone 2” hazardous area. The station was equipped with a purge and pressurized system that complied with ABS MODU rules and NFPA 496.238 The purge system was designed so that the contents of theses spaces were “safe” within the Zone 2 area. The station had two fully redundant pressurization fans (each providing 100% redundancy), with the second fan starting automatically upon failure of the lead fan. Ventilation supply fans for these spaces were located outside of a hazardous area.239 The BOP control panel, which itself is a purged system, was located within the purged DWS, creating a purge redundancy.240

Figure 7

The BOP control panel purge system was designed to maintain positive pressure relative to the pressure outside the panel. This positive pressure ensured that only air containing no combustible gases entered the panel. If the control panel lost purge, the panel as originally designed would de-energize. However, at the time of the incident, the purge/pressurization system for the driller’s BOP control panel operated in “bypass” mode so that it would not de- energize and lose power at a critical time. This bypass was necessary because a component failure in the purge system prevented the panel from re-energizing after a loss of purge.241

F. Engines

Based on my review of deposition testimony, inspection reports, maintenance reports, and technical documents, I conclude the engines were regularly inspected, properly maintained, and fully functional. The engines were equipped with multiple redundant overspeed protection devices that were appropriate, sufficient, regularly inspected, properly maintained and fully functional. The engines were also equipped with charge air cut off devices (often referred to as a

241 Deposition of Michael Williams, Vol. 1, 213:24‐214:2.

36 “Rig Saver”242) to prevent the engine ingestion and ignition of combustible gases. Notably, the installation of Rig Savers on the engines exceeded the minimum regulatory requirements. The installed Rig Savers were appropriate, sufficient, regularly inspected, properly maintained, and fully functional. There is no evidence that the engines and the substantial and redundant protection devices on the engines did not operate as designed. The vast cloud of combustible gas that enveloped the vessel resulted in numerous potential ignition sources in the vicinity of the engines and all across the rig. Accordingly, I do not believe anyone can definitively determine the ignition source of the initial explosions on the Deepwater Horizon, nor am I able to form an opinion or conclusion as to whether the engines were the source of ignition. An ignition source and blast analysis is beyond the scope of this report.

1. Engines Overview

The Deepewater Horizon’s main and emergency power arrangements were in compliance with applicable statutory requirements and Class rules243 and set up to operate in a manner consistent with Dynamically Positioned (DP) design philosophy.244

The Deepwater Horizon was equipped with six Wartsila Vasa 32 engines connected to six ABB AMG 0900 AC generators. Each engine was 18 cylinders and was equipped with two ABB VTR 354 turbochargers. These engine/generator (E/G) sets provided the main and emergency power for the rig. These E/G sets were certified at initial construction and, through subsequent inspections by ABS, were found to be in compliance with all applicable rules, regulations, and specifications.245 The Deepwater Horizon’s Simrad Vessel Control System (SVC) was provided, commissioned, and tested by Kongberg-Simrad. The main engines were controlled by the SVC. This system monitored, logged, and displayed all engine and generator alarms at panels located in the Bridge, the Engine Control Room (ECR), and the Drillers Workstation (DWS). In the event of an engine failure, the SVC would alarm and automatically bring the designated standby engine on line to replace the failing engine to ensure the vessel would have uninterrupted power to maintain position.246

Maintenance on main engines was performed in accordance with Transocean’s RMS II schedules247 and manufacturer recommendations.248 In February 2010, ABS completed engine inspections on all main engines as reflected by the Class survey status report,249 and William

37 Haynie of ABS testified that the engines and equipment met ABS requirements in March 2009.250 No deficiencies were noted concerning the engines. William Haynie also confirmed that the preventative maintenance system in place for the engines and equipment was being carried out correctly.251 Transocean personnel performed due diligence in the maintenance of all the engines and the associated protection devices. The report of RMS II – Equipment History report for March 2009 through March 2010 reflects the systematic implementation and execution of the maintenance schedule for the engines and the related equipment.252 Testimony from the Deepwater Horizon engineering and maintenance personnel clearly confirms that regular preventative maintenance was performed on the engines and related equipment.253 Further, they state that they were not aware of any conditions on the engines or the associated protective equipment that was in need of repair or might have caused the explosions.254 It was also stated that the engines on the Deepwater Horizon did not present any abnormalities on April 20, 2010.255

2. Shutdown Devices on Engines

and (c) a Woodward PG-EG Governor/Actuator; and (d) a Diesel Engine Speed Measuring System (DESPEMES) unit. These devices would sense any overspeed condition and either shut off fuel to the engines fuel rack or shut off intake air to the turbo chargers utilizing the Rig Saver.256 In addition, the engines were equipped with a Generator Frequency safety system

256 Deposition of James Mansfield, 26:13‐22, 31:15‐35:6.

39 which monitors the frequency being produced by the engine.257 If the frequency of an engine exceeded certain parameters, a signal would be sent to trip a breaker disconnecting the engine from the electrical system.

The overspeed devices on the main engines met all applicable regulatory rules and statutes. The overspeed devices had been approved and tested by ABS at initial construction258 and at subsequent annual surveys by both ABS259 and the U.S. Coast Guard.260 Crew members of the Deepwater Horizon testified that the overspeed systems were in good order and had been properly maintained.261 These overspeed devices were last tested by ModuSpec, an independent third party during the course of a Transocean initiated survey, which occurred April 1-12, 2010. All devices functioned as designed.262

(b) Charge Air Cut Off Devices (Rig Savers)

The Deepwater Horizon engines were also equipped with Rig Saver devices.263 [see Figure 10] A Rig Saver device can be described as a spring-loaded guillotine valve, which can be triggered manually or pneumatically and is mounted into a diesel engine air intake system between the turbochargers and the charge air cooler. The Rig Savers are designed to shut off charge air to the engines in the event of combustible gas entering the engine rooms or an 264 overspeed condition received from the DESPEMES unit.

41 devices were also inspected and tested during the April 2010 survey by ModuSpec, and no deficiencies in the performance of these devices were noted.270

3. Engine Air Supply and Dynamically Positioned (DP) Design Philosophy

It is important to note the relationship between the DP design philosophy and the air supply to the engines of the Deepwater Horizon. For obvious and compelling safety, environmental, and operational reasons, it is imperative that a DP vessel maintain position regardless of any single point failure in the generation of electrical power to the thrusters. Because of the serious risks that would result from a loss of power, the air supply dampers into the engine rooms of the Deepwater Horizon were specifically designed to not close automatically. Consistent with the application of DP design philosophy, to close these engine room air supply dampers required the manual activation of the dampers by the Deepwater Horizon personnel.271

The engines on the Deepwater Horizon were set up to draw their combustion air from inside the engine rooms.272 The engine rooms are not classified or designated as a Hazardous Zone. As such, the engine rooms and the electrical equipment located therein were not designed to be exposed to combustible gases. The electrical devices installed in the engine rooms were not required by any regulation or standard to be made explosion proof, intrinsically safe or purged. As a result, each of the engine room spaces would present numerous potential ignition sources upon the invasive introduction of a combustible atmosphere.

The extensive cloud of combustible gas that quickly enveloped the Deepwater Horizon would have not only created numerous potential ignition risks in the vicinity of engine rooms and across the entire vessel. The sources for potential ignition were so numerous and widespread, I do not believe anyone can reach a definitive conclusion as to the ignition source of the initial explosions. Therefore, I am unable to form an opinion or conclusion as to whether one or more of the engines were the source of ignition for the initial explosions experienced by the Deepwater Horizon on April 20, 2010.

270 See Exhibit 88, ModuSpec Rig Condition Assessment Deepwater Horizon, at 67. 271 Exhibit 1118, Deepwater Horizon Safety System Design Philosophy. 272 See Subpoena Response of Wartsila North America to BP MDL Plaintiffs’ Steering Committee.
